One of my best friends has a beautiful Betta. And he has been in a bowl for a while, and I had a ten gallon tank lying around from when I first bought my turtle that I figured I would give it to her as a birthday present. I went and bought gravel, hydor mini heater, decoration place that doubles and an air bubler and a small 10 gallon filter.

My question is more or less about the filter. Now my turtle creates lots of waste so he has a huge filter. The one I bought for her betta isnt a whisper filter because the only ones they had were for a 50 gallon, but it is similar to whisper filter for a ten gallon tank. Is this the correct filter or is there something better. And will she need anything else for the tank.

A hydor Mini heater usually does jack for anything above a 3-4 gallon tank. I had one in a 5.5 Gallon, and it raised the temp maybe one degree? I would suggest something a little bit higher, perhaps. Maybe you could take the mini back?

I agree with Codered. I bought a min for my 4.75 and it only heated it up to 73*, but only when the house as at 70* or higher. Make sure to shop around for a good price but make sure not to buy a junk brand. Should run you $15-20.
